User online detecting method, device and system

Abstract

An embodiment of the invention provides a user online detecting method, device and system and relates to the communication field. The detecting frequency can be reduced, accordingly the expenditure of network side device resources is reduced, and the response burden of a user terminal is reduced. The user online detecting method comprises the steps of sending detection information to the user terminal; re-sending the detection information to the user terminal in a first time interval from the previous detection information sending completion time if response information reported by the user terminal according to the detection information is received within a timeout duration; re-sending the detection information to the user terminal in a second time interval from the previous detection information sending completion time if the response information is not received; confirming that the user terminal is not on line when the times that the response information is not received is larger than or equal to the preset non-response times, wherein the first time interval is larger than or equal to the second time interval, and the second time interval is larger than or equal to the timeout duration. The user online detecting method, device and system is used for detecting the user online situation.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for detecting online of a user. Background technique [0002] In a broadband network, in order to avoid continuous occupancy of network resources by offline users, network side devices usually need to perform online detection on all connected user terminals to determine whether the users are currently online. [0003] When the network side equipment detects that the user terminal currently has data traffic, it can determine that the user is currently online; The user terminal sends a set of specific packets to actively detect the current online status of the user. If the active detection of a specific user terminal fails, the network side device can determine that the user is currently offline, and the network side device can then trigger a clear command to clear the user's access record and reclaim the resources occupied by the user . [0004] In ...

AI Technical Summary

Problems solved by technology

Since each network-side device usually needs to provide services to a large number of user terminals, for the network-side device, in order to ensure the accuracy of user online detection, the detection actions for all user terminals within a period of time will be very frequent, high-frequency The detection will greatly increase the resource overhead of the network side equipment, and the user terminal will also increase the response burden including the large occupation of terminal resources and the power consumption of the terminal in order to respond to frequent detection.
